Enables more generic use of the fixture facilities
without dependency on the YAML format, for example
when creating fixtures from Behat step definitions.
Note: The YamlFixture class needs to be created via
Injector::inst()->create('YamlFixture') now,
direct instantiation is no longer supported.
- Moved some docs around to reflect this change
- Described how to symlink from vendor/bin/phpunit
- Added note about browser-runs not being recommended
- Added more examples on how to run through "sake",
to complement the existing descriptions for "phpunit"
